Abstract: The intention is to develop a framework, in particular for box bodies of lorries, from a plurality of structure joints, it being possible for the individual profiles to be arranged at an angle of up to 10 DEG  to the centre line at the connection point. It is intended to make possible the construction of non-right-angled frameworks. The framework comprises a plurality of structure joints of individual profiles which are arranged at an angle to one another and, towards the connection side, are designed as U profiles. At least one corner angle is inserted into the U profiles of one of the individual profiles and a further individual profile is fastened to this corner angle, more specifically in such a way that a half-shell (8) open towards the mouth of the U and having at least one opening (9) towards the base of the U is arranged between the two limbs of the U profile (1, 2). A threaded piece (5) having a contact face (10) curved towards the half-shell (8) is inserted into the opening (9), into the interspace between the half-shell (8) and the base of the U, and a corner angle (3) of convex design is inserted into the half-shell from the opposite side and screwed to the threaded piece (5). The framework can be used, in particular, for box bodies of lorries. <IMAGE>

Abstract: The motion of the blank holder (15) can be converted by a hydraulic unit of the drawing apparatus into a simultaneous but opposite motion of the drawing punch (17). The hydraulic unit has a central working piston (12), an annular piston (13) surrounding the latter, and a cylinder (10d) surrounding the annular piston. The working piston (12) and the annular piston (17) can be pressurised from hydraulically separated cylinder spaces (51, 52; 48) which communicate with one another via at least two alternative flow paths (lines 20; 20a; 20b). Due to their different hydraulic design, the flow paths entail a pressure variation on a different pressure level in the intercommunicating cylinder spaces (51, 52; 48). A pressure transducer (21) detecting the pressure of the hydraulic fluid in the cylinder spaces (51, 52; 48) connects up the alternative flow paths when limiting pressures are exceeded. It is thereby possible to manufacture even drawn components which are extremely difficult as regards deformation profile and/or material and/or drawing depth without the necessity to sacrifice the cost- and space-saving construction of the drawing apparatus.

Abstract: A system is provided for the separation of oil from oily water particularly where the oily water is available only at relatively low pressures insufficient to drive a hydro­cyclone separator. Particular combinations of pumps (36) and hydrocyclones (38) can be effective in these low pressure situations where the pressure boost required is not substan­tially greater than a differential pressure at which the pump begins to substantially degrade the volumetric mean size of droplets of oil in the oily water passing therethrough. This is achieved by operating the pump (36) at relatively near its maximum flow rate capacity to substan­tially reduce on a percentage basis the effect of fluid slippage within the pump. Improved techniques for analysis of oil droplet size distribution are also disclosed.

Abstract: An image processing system for inspecting an article under test to determine whether at least one selected object is correctly located on the article comprises raster scan means such as a television-type camera (12) for line-by-line scanning the article (10) to generate a video signal corresponding to an image of the article, and threshold logic (16) for converting the video signal into a first binary video signal (S3) in which at least one selected object on the article is represented by a first logic level and non-selected objects and background are represented by a second logic level. A first image store (19) stores a second binary video signal (S2) corresponding to a master image of the article in which the selected object is not represented but instead in which the region of the article within which the selected object should lie is represented. Also, a second image store (20) stores information defining the correct area of the selected object on the article. The lines of the second binary video signal (S2) are read from the first store (19) in synchronism with the lines of the first binary video signal (S3), and means responsive to the first and second binary video signals measures the degree of overlap of the selected object with the respective region within which such object should lie. Finally, the measured degree of overlap of the selected object with the correct area of such object is determined.
